判断手机是否安装应用市场：

public static boolean hasAnyMarketInstalled(Context context) {

        Intent intent = new Intent();

        intent.setData(Uri.parse("market://details?id=android.browser"));

        List<ResolveInfo> list = context.getPackageManager()

                .queryIntentActivities(intent,

                        PackageManager.MATCH_DEFAULT_ONLY);

        return  != list.size();

    }
